My invention relates to electric lightingfixtures und particularly to aineens Jfor intensifying the light in a. desired direction.

,ln Standard types of electric lightingh lixtures 03": the well-corrierior hanging variety, it is necessary that one use relatively l" h wattagebulbs in order to obtain the requi Y downward illumination for readingor other purposes. The reoson for this is that innecessary einount otlight is dispers Cl ceY ward. The modern trend et interior decorotion istoward solitligjhting of the wells und ceilings through the inediuni oli`low wuttege bulbs or ornmnentel floor or telole` linups, either o?which ureconducive to eye when used 'for rondine; iurposcs. lilithrespect to the wall or'door ninps, their 'ort' effect is spoiled whenbulbs of suliciein wettegge 'for residingpurposes ure applied., and re-`tlectoiscunnot be used with such lonips witl out detructing 'troni theappearance thereof.

Brietly summarized, the present light ingl xtures require excessivelyhigh wattage bulbs for reading purposes, the use ot which producesglaring' ceiling' and well illuminetion and inertistic effects in iioorindie-,ole loinps,-all ot this being` contra to the present day theoryof interior d Ycorution which uelnzinds soft ceiling und wollillumination.

Furthermore, the use of high wattage bulbs is expensive in currentconsumption.

It is, therefore, the primary object of niy invention to overcome theobjections noted und to provide ineens whereby :i low wetten-e bulbnitty be availed of to preserve the sott toned illumination of ceilingsand walls, but which will at the saine tiine produce the bri glit,concentrated light necessary for reeding,- Aund kindred purposes.

/lnothor object of the invention is the provision ot en appliance whichis capable oi upplicution to standard types of lighting` tire tureswithout changing; the relative positions fie ornamental shades thereof,without deli-acting 'from their attractiveness.

A further and more limited object et the invention is to furnish enappliance for the purpose speciiied which involves un iinprovec e1;-tensible fixture plug having` s bulb receiving; socket and reflectorassociated therewith, the

The foregoing' and other objects of the in. 55 vention ure attained byineens of s novel coinbination end arrangement of parts to behereinafter described und claimed, and in order that the same may bebetter understood, retcrence is hed to the accompanying drewin forming uport of this specification. drawings illustre-.te wl'iut l now regardpreferred embodiment of the invention is to be understood thatvuriouschung modifications may be inode ther ...t a departure from the'spiritand scope or the subject matter clciined. i

In the drawings, wherein the seine referencechsructers designate thesaune ports in Figure l is u. longitudinal sectional view et Y the upiliunce in association with u lmnp iii;n ture:

Referring specifically to the drawings particularly to Figure l, itisnotedthut e ventionul lmnp linture shown includ lmnp soclet l carrying;`u shade S. ln cu ing out the invention 'ie plugged end 2 of theextensible socket ine-inl is screwed into the lmnp 4rlirture socliet l,thc 90 extensible socket ineinbcr coinprehendir t billar telescoping'sections 8 und The n u :j .Jn en inwardly crnnped ond flange 3a cngegthe beveled circumferential shoulder 2 ot plug to thereby hold the plugend against u supperting` flange 3b carried inwardly 'of the tendthrough closed longitudinal slots 4 in the section or member 3. Thus thesections 3 and 5 of the socket are extensibly connected and may be boundin a predetermined set position by tighting of screws 7.

An insulating lining 8 within the extensible socket section 5 separatesthe porcelain contact carrying base 9 and its associated lamp'receivingsocket 1() from the wall of socket section 5, it being understood thecontact carrying base is frictionally held in place within said section.

Figures 1 and 4 clearly show that connection is made between the contactcarrying base 9 and its lamp socket 10 by means of' a U- shaped stamping12 screwed to the base as at 12 and engaging inturned flange portions10'* of the socket 10.

The end contact point of the lamp plug 11 bears against a center contactpiece c, secured to the base 9 by a screw b which also secures anL-shaped conductor 14 thereto, the latter having an upstanding arm 14ahoused in one of the two side grooves 13 of base member 9. The othergroove 13 receives the upstanding arm 12b of the U-shaped stamping 12,as shown. Lamp socket 10 is electrically connected to the plug end 2 ofextensible socket section 3 by the flexible wires W secured as at 15 toelements 14, 14 and 12, 12".

The lower end of the extensible plug section 5 is screw threaded asindicated at 5a to receive the internally threaded annular ring 16 whichis formed with diverging arm 17 having at their ends transverselydisposed reflector supporting portions 18 of arcual form as best shownin Figure 5.

Referring to Figure 1, the reflector 19 is depicted in operativeposition and supported by the ring arms 17. Inasmuch as arms 17 aredivergent, the edges of the central opening 19 of the reflector arespaced from the lamp bulb 11 and light is permitted to pass upwardlythrough the space 20 so produced to illuminate the ornamental shade Sand cast a soft illuminating glow upon the walls and ceiling of theroom. The reflector 19 concentrates the major portion of the light raysdownwardly and by reason of this a relatively low wattage lamp willfurnish just as strong a ra-ding light as would a high wattage lampwithout the reector. Also the objectional brilliant illumination of thewalls and ceiling is obviated.

It is believed to be obvious from the drawings that the extensibility ofthe socket 3, 5 enables the reflector to be adjusted to any desiredposition to suit the particular form of the ornamental lamp shade S.With shades of large diameter the reflector 19 may be positioned withinthe confines of the shade, this being manifest from an inspection of thedrawings.

The reflector 19 may be made of different materials and shapes toharmonize with the various kinds of lamp shades.

Having thus described my invention, what I cla-im as new and desire tosecure by Letters Patent is 1. The combination with the bulb receivingsocket of a lamp fixture, of an extensible plug having one end insertedin said socket and having a bulb receivin socket at the other end, areflector carried y said plug and adjustable therewith, a shadesupported by and above said reflector and movable therewith, wherebysaid extensible plug is substantially enclosed by the shade andreflector.

2. The combination with the bulb receiving socket of a lamp fixture, ofan extensible plug having one end inserted in said socket and having abulb receiving socket at the other end, a reflector carried by said plugand adjustable therewith, a bell-shaped shade resting on said reflectorand enclosing said socket and extensible plug and movable therewith.

3. The combination with the bulb receiving socket of alamp fixture, ofan extensible plug having one end inserted in said socket and having abulb receiving socket at the other end, a reflector having a centralopening and being supported by an open support depending from said plug,said open support extending through the reflector, said reflector beingadjustable with said plug, a translucent shade supported by and abovesaid reflector and movable therewith, whereby said extensible plug issubstantially enclosed by the shade and reflector.

4. The combination with a bulb receiving socket of a lamp fixture, of aplug having one end inserted in said socket and having a bulb receivingsocket at its other end, said plug bcing adjustable in the manner tomove its receiving socket toward and from its opposite end, a reflectormounted on the sockcted end of said plug and adjustable therewith, ashade mounted upon the upper surface of the reflector and movable withthe same said shade enclosing said socket and extensible plug.

In testimony whereof I affix my signature.

CORNELIUS MAASHANT.
